Interference measurements and management in directional mesh networks

A centralized node configured to perform interference measurement in a mesh network, the centralized node comprising:

• a processor configured to partition the nodes in the mesh network into a plurality of non-overlapping clusters based on topology information of the mesh network and distance between the nodes in the mesh network, wherein nodes within a non-overlapping cluster can decode each other's beacon transmissions;
• a receiver configured to receive interference measurement reports from the nodes in the mesh network;
• the processor configured to generate a plurality of edge clusters, wherein each of the plurality of edge clusters includes at least one node in each of two non-overlapping clusters that observe mutual interference above a predetermined threshold;
• the processor configured to generate an interference measurement schedule for the plurality of non-overlapping clusters and the plurality of edge clusters, wherein interference is measured on the plurality of edge clusters before interference is measured on the plurality of non-overlapping clusters, and wherein interference is measured in parallel on the plurality of non-overlapping clusters;
• a transmitter configured to send cluster membership information for the plurality of non-overlapping clusters and the plurality of edge clusters and the interference measurement schedule to the nodes in the mesh network;
• the receiver of the centralized node configured to receive, from a first node, a notification of an error during data transmission to a second node;
• and
• in response to the received notification, the transmitter of the centralized node configured to trigger the first node to perform resource orthogonalization.
